Align public docs and maintainer guidance with the current 1,304-skill catalog state and v8.4.0 release copy.
Refresh README credits for newly imported external sources, update user-facing count references, and document the post-release docs realignment in the changelog and walkthrough.
Import and normalize new skills from anthropics/skills, marketingskills, claude-seo, and obsidian-skills.
Align imported skills to repository validation rules, document provenance, and sync generated registry artifacts after the import.
Update the maintainer and user walkthroughs so they reflect the
completed 8.2.0 release publication instead of the pre-release ready
state.
Capture the final PR merge set, issue closure state, and the exact
release commands that were executed on main.
Update the Claude marketplace entry to use a schema-valid relative source path and add a regression test so invalid marketplace sources fail in the local suite. Also document the maintainer workflow used for stale PR metadata and fork-gated Actions runs.
